Need help with my routine.

I now work through the night. Usually from 11pm or midnight 6 to 7 in the morning, sometimes 8. Ever since, it seems that astral projection has been a lot harder for me, when it is 6 7 or 8 in the morning, i would try to get to sleep, usually takes me and hour or so, i wake up usually at 2, 3, 4 or sometimes 5 in the afternoon, when i usually do my consciousness is usually very low, and i am sometimes unable to tell myself to go lie on my back and try to get in the vibration stage. Because i cannot get into the vibration stage when i lie on my side for some reason. The problem is that waking up in the afternoon there are a lot of noises going on outside in comparison to the morning, when i try to block them out they do not always work. I have earplugs they also do not always work. I need some advice on how can i start projecting or at least reach the vibration stage with this sleeping pattern?
